Viral nervous necrosis (VNN) is a worldwide disease affecting several species of cultured marine fish. In Korea, VNN has been identified in several species of cultured marine fish. In this study, the authors present data of the amplified nested polymerase chain reaction product (420 bp) of 21 nodavirus strains from different species of apparently healthy wild marine fish on the southern coast o...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...

abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
the application of e-learning systems - as one of the solutions to the issue of anywhere and anytime learning – is increasingly spreading in the area of education. content management - one of the most important parts of any e-learning system- is in the concern of tutors and teachers through which they can obtain means and paths to achieve the goals of the course and learning objectives. e-learn...
drought tolerances of 55 indigenous strains of pseudomonas fluorescens were evaluated. to assess the tolerance rate of the strains to various levels of water deficit, their growth rate in nb medium containing concentrations of 40.587, 438.838 and 548.838 g of polyethylene glycol 6000 per liter of medium were utilized. water potentials of aforesaid levels were estimated as 0, - 10, - 20 and -30 ...
a study was carried out to evaluate the secondary sexual characteristics of four strains of cocks, comprising of two (2) exotics; bovan nera black (bnb) and isa brown (isb), one (1) improved local strain, shika brown (sb) and one (1) unimproved local strain, normal feathered cock (nfc). a total of 64 birds (16 for each strain) at 36, 38, 40 and 42 weeks were used for the study. the result indic...
Background and Objectives: Lactic acid bacteria are usually involved in the preparation of fermented foods and can produce different metabolites according to their strain type. The aim of this study was to evaluate the antimicrobial, antioxidant and aggregation activities of 10 different strains of Lactobacillus plantarum isolated from native fermented foods including Koozeh cheese, fermented o...
Noncoding genetic variation is known to significantly influence gene expression levels in a growing number of specific cases; however, the patterns of genome-wide noncoding variation present within populations, the evolutionary forces acting on noncoding variants, and the relative effects of regulatory polymorphisms on transcript abundance are not well characterized. Here, we address these ques...
Staphylococcus hyicus isolates (n=207), including 150 exfolitative toxigenic and 57 non-toxigenic strains, were examined for their susceptibility to 13 antimicrobial agents by using the dehydrated 96-well MIC panel system. The frequency of their resistance to penicillin and ampicillin was 76.8% (159/207), followed by erythromycin (56%, 116/207), trimethoprim-sulfamethoxazole (28.5%, 59/207), ch...
